Stack bars show the standard error. [CO2] levels: aC (ambient [CO2], ~400 μmol mol-1) and eC (elevated [CO2], ~600 μmol mol-1). Temperature levels: aT (ambient temperature) and eT (2°C more than the ambient temperature). ANOVA p-values are show and significant effects (p <0.05) are detailed in bold. [CO2] (isolated effect of elevated [CO2]), Temp. (isolated effect of air warming) and [CO2] × Temp. (interaction of elevated [CO2] × Temp.).
